SIECIFIGATION forming part of Letters Patent No. 770,731, dated September 27, 1904.

Application filed September 29, 1902. RenewedIebruary 26, 1904. Serial No. 195,476. (No model.)

To (I/Z71 whmn it may concern:

Be it known that I, LARs ANDERson, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Feed- Valves for Explosion- Engines, of which the following is a full, clear, and exact specification.

My invention relates to the means for supplying explosion-engines with the requisite amount of fuel for each charge or explosion; and it has for its primary object to provide an improved and simple device for measuring the-charge and positively depositing the same in the explosion-chamber or other place where required.

Another object of my invention is to provide a device of this character which shall be of such a nature that it may be readily adjusted 2o automatically or by hand, as desired, whereby the speed of the engine may be governed; and a still further object of my invention is to provide an improved form of intake-valve which shall be simple and inexpensive in con- 2 5 struction and through which the air may pass for keeping the valve cool.

With these ends in view my invention consists of certain features of novelty in the construction, combination, and arrangement of 0 parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims. In the said drawings, Figure 1 is alongitudinal sectional view of my improved valve. Fig. 2 is a cross-section thereof, taken on the line 2 2, Fig. 1. Fig. 3 is a detail sectional view on the line 3 3, Fig. 1; and Fig. 4: is an en- 0 larged detail view of the plunger and a part of its operating-stem, hereinafter described.

1 represents the cylinder-head, having an induction-passage 2 leading into the cylinder 3, or these parts may represent the walls of an ordinary explosion-chamber commonly employed on this type of engine.

Secured to the head 1 is a valve-housing 4,

having a neck 5, which communicates with the induction passage 2. The interior of this housing 4: is funnel-shaped, as shown in Fig. 5 1, and it receives a conical valve 6, which is also hollow, whereby air may pass into it through either end and thence enter the neck 5, which constitutes the outlet-port of thevalve-housing, through side ports 7 8 in the lower side of the valve 6. The valve 6 is held in place snugly against its seat in the housing A by two end caps 9 10, which are secured to the ends of the housing 4 in any suitable way, and between the ends of the valve and these caps are preferably interposed antifrictionballs 11, whereby the valve may be held reasonably tight in the housing and at the same time free to revolve. When these antifrictionballs are used, it is desirable to let the balls into 5 grooves 12 in the ends of the valve and provide annular races 13, let into the inner faces of the caps 9 10, which are provided with setscrews 14, whereby the races may be adjusted with relation to the valve for keeping the 7 bearings tight. The caps 9 10 are provided with air-induction ports 15 16, respectively, whereby the inspiration stroke of the engine will draw air into the hollow valve and thence into the cylinder whenever the ports 7 8 in the valve are in register with the port 5.

Between the ports 7 8 is formed in the valve 6 a measuring-cavity 16, which as the valve is oscillated alternately comes into register with a supply-port 17 and the outlet-port 5, thus taking at each oscillation a charge of explosive liquid from the inlet-port 17 and conducting the same to and depositing it in the outlet-port 5, where it is caught by the strong currents of air entering the port 5 through 5 the ports 7 8 and converted into vapor as the mixture passes into the induction-port 2. The inlet-port 17 may be supplied with gasolene or other suitable combustible from any desired source by means of connection 18, and, 9 as shown in Fig. 2, the port 17 .and this connection, for a part of its length at least, are turned upwardly, whereby the air trapped in the measuring-cavity 16 will rise out of the cavity into connection 18 when the cavity is turned upwardly to communicate with the supply-port 17. In order that the valve may be thus oscillated, it may be connected to the the valve. Rod 27 ically by any moving parts of the engine (not shown) in any suitable way. In the example of the invention illustrated this is accomplished by a rocker-shaft 19, mounted in an extended bearing 20 on the cap 10 and havinga head 21re-, movably seated in th end of the valve 6, the outer end of the rocker-shaft-19 being provided with a rocker-arm 22, pivotallyv secured to one end of a suitable connection 23, which derives motion from any suitable source for rocking the shaft 19.

In order that the capacity of the measuringcavity 16 may be varied to suit the requirements-of the-engine, the cavity isprovided with a plunger 24:, which is formedon one end of a bifurcated stem 25, preferably made larger in diameter than the plunger 24 and having its upper end arranged in and guided by a passage 26, formed in the opposite side of valve "6, said passage also constituting a means for the insertion of the plunger and its stem. Between the two sides 5 passes a cylindrical rod 27, which is provided of the bifurcation 25 with a'beveled or inclined slide 28, Whose edges engage in inclined grooves 29, formed in the opposed sides of the bifurcated stem 25, so i that when" the rod 27 is moved longitudinally in one direction the slide 28 will raise the plungerr24, and thereby increase the capacity of measuring-cavity 16, and when moved in the opposite direction will .decrease its capacity;

The rod '27 is arranged in' line with the .axesj of the valve 6 and shaft 19, and for the sake of suflicient support the inner end of rod 27 is: journaled in a bearing-'30, bored in the inner end of shaft 19, while the other end: of shaft;

27 is mounted in an extended bearing 31,5 "formed on cap 9, so as to revolve'freely withg' may be thus actuated in any suitable way either byhand or automat-' of the automatic governors? common in this art. 'In' the "draWings'I have shown the outer end of the rod provided with; two collars 32, whereby a shifting-lever 33 may be connected thereto; for shifting the rod as desired and while the valve is'in operation. "It is of course needless to say that this rod 33 may be connected to a governor on the en-:

gine.
